TCP blocking is seen the most on mobile data connections. The LTE could be delivering whole megabytes of correct data but if that TCP connection is missing just one packet it must buffer all the rest until it can get that SACK / ACK back to the server and get the missing packet.
It happens on WiFi too but not as badly.

- tialaramex 7y agoIf there's congestion, there is a random chance of any packets being dropped, because that's how you signal congestion reliably. If there's neither congestion nor wireless links on the route between you and the server neither this, nor most other performance considerations matter to you, that's nice you're already getting the best possible outcome.
